What's nice for me personally is that this manual probably will help me with the earlier Microkit I have, from 1975. At least I hope the backplane configuration is more or less the same. I have been held up because I am unsure which slots in the backplane, assuming it's possible that there are assigned slots, to put each card. I can see from the MPM-216 page 30-31 (I had earlier found the manual too) that my hunch was correct about specific card slot assignments. You never know for sure if you have no docs. Here is my COSMAC Microkit thread if anyone is interested in comparing and contrasting my system with what's for sale now on Ebay http://www.vintagecomputer.net/browse_thread.cfm?id=511 BIll On Fri, Aug 26, 2016 at 9:46 AM, Ben Greenfield via vcf-midatlantic < vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:

of interest to people who are into MidAtlantic computing history. there is a Cosmac Development System 1800 on Ebay, looks to be from 1977, This unit has the same chassis as the 1975 RCA Microkit, and same general layout of boards.
